Geography inherently fills a 3D space and yet we struggle with displaying
geography using, primarily, 2D display devices. Virtual environments offer a more
realistically-dimensioned display space and this is being realized in the expanding area
of research on 3D Geographic Information Systems (GISs). Traditionally a GIS has only
limited tools for statistical analysis and 3D GIS research has concentrated on the
visualization of the geographical terrain. Here we discuss linking multivariate
statistical graphics to geography in the highly immersive C2 virtual reality environment
at Iowa State University using mid-Atlantic streams data.
